Electronic Soup

What we are are looking for are self-organizing molecular structures for electronic systems. These structures would be in a fluid carrier the “soup”. How farfetched is this, and what purpose would it serve?
Coming from a TV engineering background I was looking for a way to get displays which would show off 8K TV as envisioned by NHK etal. The further I got into this the more I realized that this would be an enabling technology similar to 3D printing.
The “soup” could be thought of as similar to the primordial soup of pre-evolutionary oceans, but instead of waiting for millions of years we would design the bits required to make functioning systems. Putting up a wall size screen would be as simple as taping a conducting strip at each end, painting the wall and then turning on the power. What do we need to get there?
Light emitting structures that will float in the soup and then connect themselves together when the power is turned on should be pretty simple. OLED displays made with inkjet technology are already in the labs. So think of an engineered particle with a built in lens and a couple of transistors. When current is applied to the surface the particles will hook up via the path of least resistance, first vertically then horizontally. Once the connections are made a little extra voltage will lock them in place and the excess can be wiped off or left as redundancy.
Once the manufacturing capacity is in place these particles will be so cheap that they may be thought of as disposable. Configurable antenna arrays in clothing will allow for incredible increases in bandwidth for mobile applications. Rumors already abound about invisibility cloaks, these will require light receptors as well. If we add sensors and transmitters for gaseous molecules we can retrieve and transmit sounds and microwaves.
So how would these particles self organize to provide whatever functionality is required? In the same way that cells attach to each other to make plants or animals.
Who is researching this stuff and what sort of budgets are being applied? We are not talking about molecular electronics, which is bedeviled by quantum effects and needs a lot more theoretical work. The challenges to building cell sized structures need to be solved by engineers, there is no new science required. Simulations of how these structures connect together to form functioning units should be a simple programming problem. These simulations will tell us what additional logic will be required at the cellular level.
